re: Who is the most savage player to ever put the uniform on for Bama?

Yes, Paul Bryant was possibly the toughest and meanest player ever for Alabama.

He played vs Tennessee with a broken leg.

In 1979/1980 as he was finishing his career and life, Bama played GT, coached by Bill Curry, at Legion Field. Curry said that Bryant met him in an entrance onto the field and grabbed him by his pants belt and jerked him up off of the ground and just stared at him in an act of intimidation. Curry said it worked.

This was consistent with Coach Bryant's reputation, though he was usually respectful to coaches and players. Friends with many coaches. It was a different world then :-). He sometimes came down from his tower at practice to physically manhandle a player. He did this into his 60s. He had hands like skillets.

Mike Ford was also reportedly a savage - he definitely played like one on some of Alabama's mediocre late 60s teams. 187 lb DE, who always seemed to make the big play.

Rolando McClain like others have noted. Tough, mean and serious about football.
Rueben Foster hit like no one else, along with Woodrow Lowe.

Someone mentioned Pat Trammel, who was Coach Bryant's favorite; he would become a medical doctor. Bill Oliver said that all of the QBs, of which he was one, 7 or 8 of them, were in a room, there was some discussion about who would become the starter. Trammel took out a big hunting knife and stabbed it into the table claiming that there would be no further discussion, he was the QB. And though he was not a good athlete or passer, he would be the starter and lead Bama to its first NC under Coach Bryant. You can see why Coach Bryant loved him. They were two peas in a pod - tough, mean and really smart.
